Archaebacteria

  • unicellular
  • lives in extreme habitats
  • one of the first organisms to inhabit the Earth
  • lives in places such as
    • hot springs
    • salty lakes
    • swamps
Archaebacteria lives in an anaerobic environment meaning without oxygen, it is also a thermophile which is a heat lover. Other characteristics of this organism is methanogenus and helophile meaning its produces methane gas and is a salt lover.


Eubacteria

  • common bacteria
  • most use oxygen but few cant live in the presence of oxygen
  • decomposers
  • used in food making
  • can cause bacteria
  • bioremidiation
Eubacteria is very useful because it decomposes and it is needed for humans to live on Earth, bioremdiation means that the bacteria can eat oil spills.

Shapes of Bacteria include cocci which is round, bacilli which is rod shaped, spirilla which is spiral, planes that is staph, and chains that is strepto.

Ways to classify bacteria is by gram staining and this is a process that stains the bacteria to either a purple or pink color. When positive it is purple and while negative it is pink. This procedure is used to tell what type of wall the bacteria has.
